Space Horizon was founded by Arno Wielders, MSc in September 2004 . Space
Horizon is a project agency which is focused on technical and educational
projects in Space Exploration within the institutional and the commercial
markets. Arno Wielders has worked in space projects for Dutch Space, TNO
TPD, ESA and NASA.

Arno Wielders
(1973) got his masters degree in Physics in 1997 from the Free University
of Amsterdam. After graduation he was hired by the Leiden Observatory
from the Leiden University to work at Dutch Space in the Very Large Telescope
Interferometer Delay Line project. In 2002 he received his TWAIO (two
year PhD like research) certificate and started as a research scientist
at the Space Department of TNO TPD in Delft. At TNO TPD he was heavily
involved in the Ozone Monitoring Instrument (OMI) project recently launched
by NASA. He was also responsible for doing research in metrology systems
for formation flying satellites, which included project proposals related
to several missions for ESA:

DARWIN,
an European interferometry mission consisting of several free flying
satellites with telescopes to look for other Earths and to do high resolution
imaging of extragalactic objects.

SMART-2,
a precursor mission for LISA and at that moment (2002) DARWIN, in which
a number of critical technologies needed for a successful Darwin and
LISA missions are to be tested in space.

In 1998 he co-founded
the Mars Society Nederland, part of the international Mars Society with
the aim of promoting and supporting a human mission to the Red planet.
He was involved in a number of events, such as the symposium "Mars;
a living planet" in 2001 in Delft and the Second European Mars Society
Convention in 2002 in Rotterdam. After six years he left his chairman
position at the Mars Society Nederland, but is still involved in a number
of their projects.

One of his main
research interests is comparative planetology in which the planets of
the Solar System are being studied and compared to gain knowledge in the
origin and evolution of planets and planetary systems. Therefore he is
involved in a number of initiatives in creating a larger planetary scientific
community in the Netherlands.
